That’s quite a reach there. Of course I don’t think that. But just saying ‘duh use menstrual cups’ is a classist response. Where resources are more scarce they need to be prioritised, and so some people may not have water or fuel to spare to boil a menstrual cup, or the privacy to do it in eg if a stove is shared. Let alone access to menstrual cups’ in the first place (which cost around £30 in the UK and so are already priced out of the range of a lot of people on low incomes).
